GAS-BURNER.

Specification of Letters Patent.

Patented May 18, 1920.

Application filed January 30, 1919. Serial No. 273,960.

To all whom it may concern.-

Be it known that I, DURWARD B. IcoU, a citizen of the United States, and resident of Lakewood, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Gas-Burners, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

The objects of the invention are to provide a burner for natural gas in which complete combustion of the gas is produced by the impinging of the gas at a predetermined distance from the jet orifice against a channel or arch shaped baffle or commingling plate, in which the gas and surrounding air and that carried upward by means of the jets, under pressure, are thoroughly commingled, and in which the heat of the bafile plate acts to thoroughly rarefy the mixture of gas and air, and produces immediately a more highly combustible mixture. In this manner, a greater amount of oxygen is commingled with the gas and no deposit of carbon and no objectionable odor remains behind.

The invention is particularly adapted for use in the combustion chambers of stoves or furnaces since the heat is confined locally by the form of the deflecting baffle plate, and the heated gases or products of combustion are directed laterally against the sides of the combustion chamber so that wherever the burner is located, the heat can be locally applied, and will not be immediately carried away out of the chimney.

Further advantages are found in the fact that no additional mixer or commingling chamber is required to produce a combustible form of vapor, and no adjustment is required of the parts to adapt it to variations in the pressure of the gas supply, which in the case of natural gas, is subject at times to a very low condition of pressure. By means of the ordinary valves all adjustments required can be made.

A further advantage is found in the use of a superimposed baffle plate of the confining character described and in the fact that the several jets in adjacent burner tubes will become ignited from each other and no gas from an open jet can escape without ignition on account of the distributing properties of the overhead bafile. A further advantage of the invention is that the burner is perfectly safe since so long as there is any pressure at all the flame cannot go out, which is not possible when mixers are used.

The invention is hereinafter more fully described, shown in the accompanying drawings and specifically pointed out in the claims. In the accompanying drawings Figure 1 is a perspective of a preferred form of the device. Fig. 2 is a plan thereof, showing two burners, Fig. 3 is a side elevation of a burner showing a single arch and central dividing rib.

In these views is a gas supply ipe provided with minute burner jets B, spaced thereon at regular intervals. C is an arched or longitudinally recessed baffle plate superimposed thereon and vertically spaced therefrom at a sufficient distance to permit the jets which issue with considerable force to compel the surrounding air to follow them and together with the air to strike against the arched recess or recesses in the baflle plate above.

The jets expand greatly as they rise and 7 together with the commingled and impelled air carried with them are momentarily retained in the recessed plate above and after being intimately commingled thereby are deflected in a thoroughly rarefied condition toward the sides of the plate in a divided stream and when ignited the flames roll outwardly and laterally upon both sides of the bafiie plate. In use the force of the jets will carry the gas and impelled air nearly to the plate before ignition will take place so that there is no danger of the gas burning in an unmingled form.

A support D is secured to the inner extremity of the burner tube by means of the elbow E, and a tapered projection F upon one member is received in a socket Gr in the other member, which forms a rigid joint and makes'the parts easy to assemble. In Fig. 1, a double arch is formed in the baffle plate and in Fig. 3 a single arch C is shown and a central depending flange or rib C in both figures diverts the commingled air and gas to the outer sides of the plate. The plate curves upwardly and outwardly from said rib on each side. Valves H, H, are shown for controlling the flow of gas and a common supply pipe I feeds the burners.

Having described the invention what I claim as new and desire to secure by Letters Patent is:

1. In a gas burner the combination With a horizontal tube provided with spaced burner jet openings on its upper face, of a baffle plate superimposed thereon and concaved upon both sides of'a central rib upon its lower surface to form a combined commingling and deflecting means substantially as described.

2. A gas burner for the purpose set forth comprising a burner tube provided with spaced perforations upon its upper surface, and a parallel concaved commingling and deflecting plate superimposed thereon and vertically spaced therefrom, said deflecting plate having a longitudinal rib upon its lower surface, the sides of said plate extending in arcuate form laterally from said rib, said rib serving to divert the com mingled air and gas in two directions to the outer sides of the plate.

3. A gas burner for the purpose set forth, comprising a horizontal burner tube provided With spaced openings upon its upper edge, and a baffle plate vertically spaced therefrom and concaved on its lower surface, said plate provided with a central longitudinal rib on its underside and having its longitudinal sides curved upwardly and outwardly therefrom in the form of arcs, and means for detachably supporting the baffle plate upon said burner tube.

4:. A gas burner for the purpose set forth comprising a horizontal burner tube provided with spaced jet orifices, a concaved bafie plate vertically spaced therefrom, a support secured to the inner end of said burner tube and a socket in one of said members in which the other member is inserted.

5. A gas burner comprising a burner tube having spaced jet orifices in its upper edge, and a combined commingling and deflecting plate therefor, said plate having a longitudinal central downwardly projecting rib on its lower surface, the sides of said plate curved upwardly and laterally outwardly on both sides of said central rib.

In testimony whereof I hereunto set my hand this 23d day of January, 1919.
